DevExtreme Vue - Create the Layout Grid

All ResponsiveBox elements are arranged in a layout grid according to the rows and cols arrays. Each object in these arrays configures a single row or column. Populate these arrays with empty objects to get two sets of equally-sized rows and columns.

The baseSize, ratio, and shrink settings control a row or column's size. The baseSize defines the row's or column's initial size in pixels. The size then changes according to ratio and shrink if the ResponsiveBox's size changes.

The ResponsiveBox can provide more space than rows' and columns' baseSizes require:

DevExtreme ResponsiveBox: Available width and height

In this case, the columns' width and rows' height can be increased according to ratios. If all rows or columns have the same ratio, the width or height is increased evenly. The following is an example of when ratios are different:

DevExtreme ResponsiveBox: Distribution of available width and height

If ratio applies when there is an available space, shrink applies when space is limited. After all rows' or columns' baseSizes are added up, they may be too large to fit into the container.

DevExtreme ResponsiveBox: Items overflow the container

shrink determines how much the elements should shrink to fit in this case. The higher the shrink value, the more a row or column shrinks relative to the rest of the rows or columns. The following example illustrates a situation when all elements have the same shrink value:

DevExtreme ResponsiveBox: Items shrink evenly to fit into the container

In the following image, the middle column's shrink value is more than the other columns', and the bottom row's shrink value is more than that of the top row.

DevExtreme ResponsiveBox: The middle column and the bottom row shrink more than the other columns and rows

The collections of rows and columns may differ depending on the screen's size qualifier. You can use the screen option to specify on which screen types an individual row or column should appear.
